(Warning: you'll need a realatively powerful computer to commit this exploit. Probably. I haven't tried with lower spec computers yet.)

Map hopping, as I like to call it, is an awesome yet easy to use stratergy.

If you haven't noticed already, when you drive down a road on the map, not only is the road unlocked, but the areas surrounding. This can be used to 'map hop' and quickly get around unexplored areas of the map (and also allows you to 'move' offroad quickly in a non-offroad spec).

This is what allows the exploit.

to commit 'map hopping', you first need to open up your map and zoom to the second closest zoom. This loads most of the entities and other objects near the road and is what allows for quick loading when using map hopping. Now pick an area very close to the desired unexplored area you wish to explore. Fast travel to the position, then rinse and repeat. If done quickly enough, it's possible to move faster than driving, especially when driving low level cars and crowded city areas.

Congrats. You now know how to 'map hop'.

Have fun driving/map hopping around in The Crew (whichever you prefer).
